The compounds represented by Formulae I and II can be prepared by one or more of the following methods, or variations obvious to one skilled in the art, as described below in Schemes 1-20. The definitions of G, Q, X, W, n, m, p, q and R1 through R21 in the compounds of Formula 1-21 below are as defined above in the Summary of the Invention. Compounds of Formulae Ia-Ip and Formulae IIa-IIh are within the definition of compounds of Formulae I and II, respectively.
One skilled in the art will recognize that when G is O, some compounds of Formulae I and II have a plane of symmetry. Therefore, the two formulae below are equivalent. ##STR7##
Synthesis of Compounds of Formula I
Condensation of an R2 -substituted 1,4-cyclohexadiene 1,2-dicarboxylic arthydride with aniline in acetic acid (AcOH) at a temperature between room temperature and reflux, gives the dihydrophthalimide of Formula I, as illustrated in Scheme 1. ##STR8##
Treatment of the olefin of Formula 1 with borane in an inert solvent such as tetrahydrofuran at a temperature between about -78° C. and room temperature followed by addition of aqueous sodium hydroxide and aqueous hydrogen peroxide (preferably 30%) gives the alcohol of Formula Ia, as illustrated in Scheme 2. ##STR9##
Alternatively, compounds of Formula Ia can be obtained by treatment of the olefin of Formula 1 with m-chloroperoxybenzoic acid (MCPBA) in an inert solvent such as dichloromethane to obtain the epoxide illustrated in Scheme 2. Subsequent treatment with a reducing agent such as sodium borohydride affords the alcohol of Formula Ia.
Compounds of Formula Ib (Scheme 3) are made from compounds of Formula Ia. The R22 group is a subset of the R1 group in compounds of Formula I. For example, treatment of the alcohol of Formula Ia with diethylaminosulfur trifluoride (DAST) at a temperature between about -78° C. and 100° C. in an inert solvent such as dichloromethane gives the fluorinated product of Formula Ib wherein R22 =F. ##STR10##
Compounds of Formula Ia can also be converted to the R22 =Cl, Br, and I compounds of Formula Ib using methods known to those skilled in the art (see March, J., Advanced Organic Chemistry, (1992), 4th Ed., John Wiley and Sons, Inc., pp 382-384). The hydroxy group in compounds of Formula Ia can be acylated by known methods to prepare the alkylcarbonyloxy and haloalkylcarbonyloxy derivatives (see March, J., Advanced Organic Chemistry, (1992), 4th Ed., John Wiley and Sons, Inc., pp 346-351). In-addition, the hydroxy or halo group can be convened by known methods to afford the alkoxy and haloalkoxy derivatives (see March, J., Advanced Organic Chemistry, (1992), 4th Ed., John Wiley and Sons, Inc., pp 342-346).
Compounds of Formula Ib wherein R22 =F can also be prepared directly from the unsaturated compound of Formula 1 by the addition of hydrofluoric acid. G. A. Olah and X. Y. Li, Syn. Lett., (1990), 5, 267 and N. Yoneda et al., Chem. Lett., (1984), 7, 1241 describe methods for the addition of HF to double bonds.
For some compounds of Formulae Ia and Ib wherein R2 is other than hydrogen, the R2 substituent is more conveniently introduced along with the R1 substituent. This is especially the case when R1 and R2 are attached to the same carbon atom. For example, compounds of Formula Ib wherein R1 and R2 are gem-difluoro (compounds of Formula Id) can be prepared as illustrated in Scheme 4. Oxidation of the alcohol of Formula Ia wherein R2 is hydrogen with pyridinium chlorochromate (PCC) in an inert solvent, such as dichloromethane, affords the ketone of Formula Ic. Subsequent treatment with DAST in dichloromethane as described above affords the gem-difluoro compound. ##STR11##
Similarly, as shown in Scheme 5, R1 and R2 can be introduced together when they are attached to adjacent carbons. Treatment of the olefin of Formula 1 (where R2 is hydrogen) with NBS or NCS and water in an inert solvent such as DMSO at a temperature between about 0° C. and room temperature gives the bromohydrin of Formula Ie. Compounds of Formula If are made from compounds of Formula Ie. Treatment of the alcohol of Formula Ie with DAST at a temperature between about -78° C. and 100° C. in an inert solvent such as dichloromethane gives the fluorinated product of Formula If. Debromination or dechlorination can be achieved by treatment of Formula If with tributyltinhydride and AIBN at a temperature between about 0° C. and 150° C. in an inert solvent such as benzene or toluene to give the product of Formula Ig. ##STR12##
Yet another method for preparing compounds of Formula Ib is illustrated in Scheme 6. The appropriately substituted phthalic acid esters of Formula 2 can be reduced to form the cyclohexene diester of Formula 3 by hydrogenation over platinum (IV) oxide. Subsequent treatment with acid, such as hydrochloric acid affords the phthalic anhydride of Formula 4. Treatment with an aniline in acetic acid (AcOH) at a temperature between room temperature and reflux as described above, gives the dihydrophthalimide of Formula Ib. ##STR13##
Compounds of Formula I wherein R2 is hydrogen can be prepared by the methods illustrated in Schemes 7-10. Condensation of 3,4,5,6-tetrahydrophthalic anhydride (q1 =2) or its 5-membered ring homolog (q1 =1) with anilines in acetic acid (AcOH) at a temperature between ambient and reflux temperatures gives an imide of Formula 5, as illustrated in Scheme 7. ##STR14##
Treatment of the imide of Formula 5 with N-bromosuccinimide (NBS) in an inert solvent such as carbon tetrachloride at a temperature between ambient and reflux temperatures, in the presence of light, gives the allyl bromide of Formula Ih, as illustrated in Scheme 8. ##STR15##
Hydrolysis of the bromide of Formula Ih using aqueous dimethyl sulfoxide (DMSO) at a temperature between about room temperature and the reflux temperature of the solvent gives the alcohol of Formula Ii (Scheme 9). ##STR16##
Compounds of Formula Ij (Scheme 10) can be made from alcohols of Formula Ii. For example, treatment of the alcohol of Formula Ii with diethylaminosulfur trifluoride (DAST) at a temperature between about -78° C. and 100° C. in an inert solvent such as dichloromethane gives the fluorinated product of Formula Ij wherein R22 =F. Compounds of Formula If can also be converted to compounds of Formula Ij wherein R22 =Cl, Br, I, alkylcarbonyloxy and haloalkylcarbonyloxy as described above for compounds of Formula Ib. Likewise, compounds of Formula Ij wherein R22 =alkoxy or haloalkoxy can be derived from the hydroxy (Id) or bromo (Ih) derivatives by known methods (see March, J., Advanced Organic Chemistry, (1992), 4th Ed., John Wiley and Sons, Inc., pp 382-384, 346-351,342-346). ##STR17##
Compounds of Formula Ik can be prepared by the method illustrated in Scheme 11. Treatment of β-keto esters of Formula 6 with trifluoromethanesulfonic anhydride (triflic anhydride) affords the vinyl triflate of Formula 7 using conditions described in Aldrichimica Acta, (1983), 16, 15. Carbonylation of the vinyl triflate using carbon monoxide, palladium (II) acetate (Pd(OAc)2) and 1,3-bis(diphenylphosphino)propane (dppp) provides the intermediate amide of Formula 8 (see R. E. Dolle et al., J. Chem. Soc., Chem. Commun., (1987), 904; and S. Cacchi et at., Tetrahedron Lett., (1985), 26, 1109 for a discussion of this carbonylation methodology). Cyclization occurs under basic conditions and/or upon heating to give the imide of Formula Ik. ##STR18##
The β-ketoesters of Formula 6 are known or can be prepared by methods well-known in the art. For example, the ethyl ester of Formula 6 wherein X is S, q1 is 2, and R1 and R2 are H is commercially available from Emka-Chemie, Schlusselberg, Germany. When X is a nitrogen-based group, it may be desirable to perform the reactions on a protected form of the nitrogen and introduce the desired X group after formation of the imide ring.
Compounds of Formula I wherein G is S can be prepared as illustrated in Scheme 12. Treatment of the amide-ester of Formula 8 with Lawesson's reagent (2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide) affords the corresponding thioamide of Formula 9. Cyclization under the conditions described above (base and/or heat) affords the thioimide of Formula II . In instances where heat is necessary to convert the amide to the thioamide using Lawesson's reagent, the cyclized product may be obtained directly. ##STR19##
Compounds of Formula I wherein n+m=2 and the R22 -substituent on the cyclopentene ring is not in the allylic position (compounds of Formula In) can be prepared as illustrated in Scheme 13. ##STR20##
The bromo compound of Formula Im can be prepared by allylic bromination as described above and illustrated in Scheme 8. Treatment of the bromide with a strong base such as 1,8-diazabicyclo 5.4.0!undec-7-ene (DBU) leads to elimination of HBr and the formation of the unsaturated compound of Formula 10. Hydroboration using the conditions described above and illustrated in Scheme 2 affords the alcohol of Formula 11. If the ratio of alcohol regioisomers obtained in the hydroboration is undesirable, a larger mount of the desired regioisomer may be obtained by treatment of the olefin with mercuric acetate and water followed by demercuration with sodium borohydride. Conversion of the alcohol to the desired R22 substituent can be accomplished in a manner analogous to those previously discussed (see above).
Compounds of Formula Io, compounds of Formula I wherein n or m is zero can be prepared as illustrated in Scheme 14. Treatment of the anhydride of Formula 12 with the appropriate aniline in acetic acid (HOAc) provides the imide of Formula Io. Arthydrides of Formula 12 are known or can be made by well-known methods. For example, the compound of Formula 12 wherein X is S, R1 and R2 are H, and q1 is 2 is described in U.S. Pat. No. 4,164,404. ##STR21##
Synthesis for Compounds of Formula II
Treatment of the R2 -substituted tetrahydropyridazine (q=2) or pyrazoline (q=1) of Formula 13 with two equivalents of ethyl cyanoformate affords the 1,2-carboxylate of Formula 14 as illustrated in Scheme 15. The dicarboxylate can be converted to the triazolidinedione of Formula 15 by contact with trimethylaluminum in an inert solvent such as toluene or dichloromethane at a temperature between 0° C. and 100° C. followed by addition of the aniline H2 NQ at a temperature between 0° C. and 100° C. ##STR22##
Treatment of the olefin of Formula 15 with borane in an inert solvent such as tetrahydrofuran at between about -78° C. and ambient temperature, followed by the addition of aqueous sodium hydroxide and hydrogen peroxide (preferably 30% aqueous) gives the alcohol of Formula IIa, as illustrated in Scheme 16. Alternatively, the alcohol of Formula IIa when q is 1 can be prepared from 4-hydroxypyrazolidine (see Kumagai, et al., Heterocycles, (1994), 37, 1521-7 for its preparation from epichlorohydrin and hydrazinc) using the process described in Scheme 15. ##STR23##
Alcohols of Formula IIa a can be converted to the halo-substituted compounds of Formula IIb by well-known methods for performing this functional group transformation (see March, J., Advanced Organic Chemistry, (1992), 4th Ed., John Wiley and Sons, Incl, pp 382-384, 807-809). For example, treatment of the alcohol with diethylaminosulfur trifluoride (DAST) at a temperature between about -78° C. and 100° C. in an inert solvent such as dichloromethane gives the compound of Formula 11b wherein hal=F. Using the methods described in March above and known to those skilled in the art, compounds of Formula IIa can also be converted to compounds of Formula IIb wherein hal=Cl , Br, and I.
For some compounds of Formula IIb wherein R2 is other than hydrogen, the R2 substituent is more conveniently introduced along with the R1 substituent. When R1 and R2 are both chlorine or bromine and attached to adjacent atoms, the halogens can be introduced in the same reaction by treating the olefin of Formula 15 with Br2 or Cl2 using standard conditions for dihalogenation. When R1 and R2 are gem-difluoro, the fluorine atoms can be introduced by treating the corresponding ketone with DAST as described above (see Scheme 4).
Compounds of Formula IIb wherein q is 2 (Formula IId can also be prepared using the reaction sequence described above starting with the tetrahydropyridazine of Formula 16 (Scheme 17). ##STR24##
Compounds of Formulae IIe, IIf, and IIg can be prepared as shown in Scheme 18. Treatment of the olefin of Formula 17 (where R2 is hydrogen) with NBS or NCS and water in an inert solvent such as DMSO at a temperature between about 0° C. and room temperature gives the bromohydrin of Formula IIe. Treatment of the alcohol of Formula IIe with DAST at a temperature between about -78° C. and 100° C. in an inert solvent such as dichloromethane gives the fluorinated product of Formula IIf. Debromination or dechlorination can be done by treatment of Formula IIf with tributyltin hydride and AIBN at a temperature between about 0° C. and 150° C. in an inert solvent such as benzene or toluene to give the product of Formula IIg. ##STR25##
Compounds of Formula II wherein G is S can be prepared as illustrated in Scheme 19. Treatment of the R2 -substituted tetrahydropyridazine (q=2) or pyrazoline (q=1) of Formula 13 with the isothiocyanate derived from Q-NH2 affords the thioamide of Formula 18. Cyclization can be accomplished by treatment of the aminoamide with 1,1'-carbonyldiimidazole and affords the thiono compound of Formula 19. In some instances, it is desirable to protect the non-acylated nitrogen of the tetrahydropyridazine or pyrazoline prior to contact with the isothiocyanate. The protecting group can be removed prior to cyclization. The thiono compound of Formula 19 can be converted to compounds of Formula II wherein G is S by the methods described above. ##STR26##
Compounds of Formula II can also be prepared by methods disclosed in EP-A-75,267 and illustrated in Scheme 20. Treatment of the urazol of Formula 20 with a base, such as sodium methoxide, sodium hydride, or n-butyllithium, in an inert solvent, such as methanol, diethyl ether, or tetrahydrofuran, at a temperature between about 60° C. and 160° C., followed by treatment with an alkylating agent of Formula 21 which is substituted at each terminus with a leaving group, affords the desired product. Appropriate leaving groups include chlorine, bromine, methane sulfonate, and p-toluene sulfonate. The R1 and R2 groups on the compound of Formula 21 may be substituted on any of the carbon atoms. Alternatively, protected forms of the R1 and R2 groups may be incorporated into 21, and then the actual R1 and R2 groups can be introduced after cyclization. ##STR27##
The anilines of formula Q-NH2 and isothiocyanates of formula Q-NCS used as reactants in the syntheses described above are known or can be prepared by well-known methods. For example, anilines where Q is Q-1, Q-4, and Q-6 can be prepared as described in U.S. Pat. No. 4,902,335, anilines where Q is Q-2 and Q-3 can be prepared as described in U.S. Pat. No. 5,053,071, and anilines where Q is Q-5 can be prepared by well known functional group transformations of known phenyl derivatives.
It is recognized that some reagents and reaction conditions described above for preparing compounds of Formulae I and II may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991).
One skilled in the art will also recognize that compounds of Formulae I and II and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.

Formulation/Utility
Compounds of this invention will generally be used in formulation with an agriculturally suitable carrier comprising a liquid or solid diluent and/or a surfactant wherein the formulation is consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible ("wettable") or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or "overcoated"). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.
The formulations will typically contain effective mounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Doffand Books, Caldwell, N.J. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, N.J., as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth and the like, or thickeners to increase viscosity.
Surfactants include, for example, polyethoxylated alcohols, polyethoxylated alkylphenols, polyethoxylated sorbitan fatty acid esters, dialkyl sulfosuccinates, alkyl sulfates, alkylbenzene sulfonates, organosilicones, N,N-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxyethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillinite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water, N,N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrrolidone, ethylene glycol, polypropylene glycol, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, tung, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy4-methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol and tetrahydrofurfuryl alcohol.
Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling; see, for example, U.S. Pat. No. 3,060,084. Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp 147-48, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in U.S. Pat. No. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. Pat. No. 4,144,050, U.S. Pat. No. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. Pat. Nos. 5,180,587 , 5,232,701 and 5,208,030. Films can be prepared as taught in GB 2,095,558 and U.S. Pat. No. 3,299,566.

______________________________________
Tests results indicate that the compounds of the present invention are highly active preemergent and/or postemergent herbicides and/or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or postemergence weed control in areas where complete control of all vegetation is desired such as around fuel storage tanks, industrial storage areas, parking lots, drive-in theaters, around billboards and highway and railroad structures. Some of the compounds are useful for the control of selected grass and broadleaf weeds with tolerance to important agronomic crops which include but are not limited to barley, cotton, wheat, rape, sugarbeets, corn, soybeans, rice, and plantation crops such as sugarcane, citrus, grapes, coffee, oil palm, cocoa, fruit trees, nut trees, banana, plantain, rubber, pineapple and loblolly pine. Preferred is the method of using compounds of Formulae I and II such as citrus, sugarcane, coffee, oil palm, rubber, cocoa, grapes, fruit trees, and pineapple.
Those skilled in the art will appreciate that not all compounds are equally effective against all weeds. Alternatively, the subject compounds are useful to modify plant growth.

A herbicidally effective mount of the compounds of this invention is determined by a number of factors. These factors include: formulation selected, method of application, amount and type of vegetation present, growing conditions, etc. In general, a herbicidally effective amount of a compound(s) of this invention is applied at rates from about 0.001 to 20 kg/ha with a preferred rate range of 0.004 to 1.0 kg/ha. One skilled in the art can easily determine application rates necessary for the desired level of weed control.
The following Tests demonstrate the control efficacy of the compounds of this invention against specific weeds. The weed control afforded by the compounds is not limited, however, to these species. See Index Tables A-C for compound descriptions.

Test A
Seeds of barnyardgrass (Echinochloa crus-galli), cocklebur (Xanthium pensylvanicum), crabgrass (Digitaria spp.), downy brome (Bromus tectorum), giant foxtail (Setaria faberii), morningglory (Ipomoea spp.), sorghum (Sorghum bicolor), velvefleaf (Abutilon theophrasti) and wild oat (Avena fatua) were planted into a sandy loam soil and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which includes a surfactant. At the same time, these crop and weed species were also treated postemergence with test chemicals formulated in the same manner.
Plants ranged in height from two to eighteen cm and were in the two to three leaf stage for the postemergence treatment. Treated plants and untreated controls were maintained in a greenhouse for approximately eleven days, after which all treated plants were compared to untreated controls and visually evaluated for injury. Plant response ratings, summarized in Table A, are based on a 0 to 10 scale where 0 is no effect and 10 is complete control. A dash (-) response means no test results.

Test B
Seeds of barley (Hordeum vulgare), barnyardgrass (Echinochloa crus-galli), blackgrass (Alopecurus myosuroides), bush bean (Phaseolus vulgaris), cheatgrass (Bromus secalinus), chickweed (Stellaria media), cocklebur (Xanthium pensylvanicum), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria sanguinalis), downy brome (Bromus tectorum), giant foxtail (Setariafaberii), lambsquarters (Chenopodium album), morningglory (Ipomoea hederacea), rape (Brassica napus), rice (Oryza satira), sicklepod (Cassia tora), sorghum (Sorghum bicolor), soybean (Glycine max), sugar beet (Beta vulgaris), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), wild buckwheat (Polygonum convolvulus), wild oat (Avena fatua) and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which includes a surfactant.
At the same time, these crop and weed species were also treated with postemergence applications of test chemicals formulated in the same manner. Plants ranged in height from two to eighteen cm (one to four leaf stage) for postemergence treatments. Treated plants and controls were maintained in a greenhouse for twelve to sixteen days, after which all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table A, are based on a scale of 0 to 10 where 0 is no effect and 10 is complete control. A dash (-) response means no test result.

Test C
The compounds evaluated in this test were formulated in a non-phytoxic solvent mixture which include a surfactant and applied to the soil surface before plant seedlings emerged (preemergence application), to water that covered the soil surface (flood application), and to plants that were in the one-to-four leaf stage (postemergence application ), A sandy loam soil was used for the preemergence and postemergence tests, while a silt loam soil was used in the flood test, Water depth was approximately 2.5 cm for the flood test and was maintained at this level for the duration of the test,
Plant species in the preemergence and postemergence tests consisted of barnyardgrass (Echinochloa crus-galli), barley (Hordeurn vulgare), bedstraw (Galium aparine), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), cocklebur (Xanthium pensylvanicum), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria sanguinalis), downy brome (Bromus tectorum), giant foxtail (Setaria faberii), johnsongrass (Sorghum halpense), lambsquarters (Chenopodium album), morningglory (pomoea hederacea), pigweed (Amaranthus retroflexus), rape (Brassica napus), ryegrass (Lolium multiflorum), soybean (Glycine max), speedwell (Veronica persica), sugar beet (Beta vulgaris), velvetleaf (Abutlion theophrasti), wheat (Triticum aestivum), wild buckwheat (Polygonurn convolvulus), and wild oat (Avena fatua). All plant species were planted one day before application of the compound for the preemergence portion of this test. Plantings of these species were adjusted to produce plants of appropriate size for the postemergence portion of the test. Plant species in the flood test consisted of rice (Oryza saliva), umbrella sedge (Cyperus difformis), duck salad (Heteranthera limosa), barnyardgrass (Echinochloa crus-galli) and Late watergrass (Echinocloa oryzicoIa) grown to the 1 and 2 leaf stage for testing.
All plant species were grown using normal greenhouse practices. Visual evaluations of injury expressed on treated plants, when compared to untreated controls, were recorded approximately fourteen to twenty one days after application of the test compound. Plant response ratings, summarized in Table C, were recorded on a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

Test D
Seeds, rhizomes, or plant parts of alexandergrass (Brachiaria plantaginea), alfalfa (Medicago saliva), annual bluegrass (Poa annua), bermudagrass (Cynodon dactylon), broadleaf signalgrass (Brachiaria platyphylia), common purslane (Portulaca oleracea), common ragweed (Ambrosia artemisiifolia), dallisgrass (Paspalum dilatatum), goosegrass (Eleusine indica), guineagrass (Panicum maximum), itchgrass (Rottboellia cochinchinensis), johnsongrass (Sorghum halepense), large crabgrass (Digitaria sanguinalis), P.J. legume (Pueraria javanica), peanut (Arachis hypoagaea), pitted morningglory (Ipomoea lacunosa), purple nutsedge (Cyperus rotundus), sandbur (Southern sandbur), smooth crabgrass (Digitaria ischaemum), sourgrass (Panicum Texanum) and yellow nutsedge (Cyperus esculentus) were planted into greenhouse pots containing greenhouse planting medium. Each pot contained only one plant species.
The test compound was formulated in a non-phytotoxic solvent mixture which includes a surfactant and applied preemergence and/or postemergence to the plants. Preemergence applications were made within one day of planting the seeds or plant pans. Postemergence applications were applied when the plants were in the two to four leaf stage (three to twenty cm). Untreated control plants and treated plants were placed in the greenhouse and visually evaluated for injury at 14 to 28 days after herbicide application. Plant response ratings, sununarized in Table D, are based on a 0 to 100 scale where 0 is no injury and 100 is complete control. A dash (-) response indicates no test result.

Test E
Plant species in the preemergence tests consisted of barnyardgrass (Echinochloa crus-galli), bedstraw (Galium aparine), bluegrass (Poa trivialis), cassia (Cassia tora), cheat grass (Bromus secalinus), cocklebur (Xanthium pensylvanicum), corn (Zea mays), crabgrass (Digitaria sanguinalis), curly indigo (Aeschynomene virginica), giant foxtail (Setaria faberii), jimsonweed (Datura stramonium), johnsongrass (Sorghum halpense), morningglory (Ipomoea hederacea), mustard (Sinapis arvensis), nutsedge (Cyperus rotundus), pig weed (Amaranthus retrofiexus), rice (Oryza sativa), sorghum (Sorghum bicolor), soybean (Glycine max), sugar beet (Beta vulgaris), teaweed (Sida Spinosa), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum) and wild oat (Avena fatua). All plant species were planted one day before application of the compound. Compounds evaluated in this test were formulated in a non-phytotoxic solvent mixture which includes a surfactant and applied to the soil surface before plant seedlings emerged (preemergence application).
All plant species were grown using normal greenhouse practices. Visual evaluations of injury expressed on treated plants, when compared to untreated controls, were recorded approximately fourteen to twenty one days after application of the test compound. Plant response ratings, summarized in Table E, were recorded on a 0 to 10 scale where 0 is no effect and 10 is complete control. A dash (-) response means no test result.

Test G
Compounds were evaluated under various conditions for their effectiveness in controlling the growth of nutsedge (Cyperus rotundus) in this test. The test compound was applied in a non-phytotoxic solvent (generally water) to nutsedge tubers which had been previously seeded into pots containing a sandy loam soil and allowed to grow for several weeks, these were treated as the post-emergence treatment. Additionally, freshly prepared pots were seeded with tubers. These treatments constituted the preemergence treatment where the covering soil was treated with the compound. In another treatment, the exposed tubers were allowed to contact the sprayed test compound directly. In the final treatment, the soil used to cover the tubers was placed in a bag and treated with the appropriate amount of the test compound. The contents of the bag were then mixed (incorporated) and placed on the surface of the seeded pots. All treatments were maintained in the greenhouse where visual ratings were made at two and four weeks after application of the test compound. Plant response ratings, summarized in Table G, were recorded on a 0 to 10 scale where 0 is no effect and 10 is complete control. A dash (-) response means no test result.

Test H
This test evaluated the effects of test compounds on monocot weeds grown in association with cereal crops such as rice, wheat or barley. In the current test, compounds were applied to the foliage of barnyardgrass (Echinochloa crus-galli) and Japonica rice (Oriza sativa) or to the surface of pots recently seeded with the test species. All test compounds were first formulated in a non-phytotoxic solvent mixture which includes a surfactant and sprayed over the foliage or soil surface to the test unit. After application of the test compound, the plants were maintained in the greenhouse under standard conditions until such time as they were visually evaluated. Plant response ratings, summarized in Table H, were recorded on a 0 to 10 scale where 0 is no effect and 10 is complete control. A dash (-) response means no test result.
